No idea. Getting a release out is slow. I thought v4.5 would have been released weeks ago but typical garbage HTML mail mostly is holding it up. Probably this one will come out as a beta instead of a full release. FWIW, David does work on the new folders and other things even though primarily he's working WinPMail right now.
